Combine red pepper powder, sugar, salt, anchovy sauce, minced garlic, sesame oil, finely chopped green onion, vinegar (optional), and sesame seeds to create the seasoning sauce.

Add jujube syrup or plum extract to the seasoning sauce for a sweet and savory balance.

Mix the seasoning sauce thoroughly until smooth and well combined.

Prepare napa cabbage by slicing it diagonally and washing it in cold water. Slice chives into small pieces.

Place the napa cabbage and chives in a large mixing bowl and add the seasoning sauce gradually while tossing gently.

Add extra red pepper powder for vibrant color and mix evenly.

Taste and adjust the seasoning to suit your preference.
